DETAILED DESCRIPTION

The present inventions will now be discussed in detail with regard tothe attached drawing figures that were briefly described above. In thefollowing description, numerous specific details are set forthillustrating the Applicant's best mode for practicing the invention andenabling one of ordinary skill in the art to make and use the invention.It will be obvious, however, to one skilled in the art that the presentinvention may be practiced without many of these specific details. Inother instances, well-known machines, structures, and method steps havenot been described in particular detail in order to avoid unnecessarilyobscuring the present invention. Unless otherwise indicated, like partsand method steps are referred to with like reference numerals.

A Method of Using Static Routing to Migrate a Shared Hosting Account

Several different methods may be used to provide and manage thedisclosed invention. In an example embodiment illustrated in FIG. 1, aHosted Account on a First Hardware Resource may be associated with aShared Hosting Internet Protocol (IP) Address (Step 100). Static routingmay then be used to migrate the Hosted Account to a Second HardwareResource using static routing (Step 110).

The example embodiments shown and described exist within the frameworkof a network and should not limit possible network configuration orconnectivity. Such a network may comprise any combination of theInternet, an intranet, an extranet, a local area network, a wide areanetwork, a wired network, a wireless network, a telephone network, orany other known or later developed network.

Non-limiting examples of network hardware resources which may be used inthe framework of the present invention may include switches, hubs,gateways, access points, network interface cards, network bridges,modems, ISDN adapters, firewalls, datacenter equipment such as fileservers, database servers and storage areas, network services such asDNS, DHCP, email and content delivery.

Static routing may include the use of fixed routes that may be manuallyentered by an administrator of a network into a network router'sconfiguration. This may require the network administrator to manuallyupdate the static route in response to resource utilization changes ifthe static route is entered into the configuration. In other words, whennetwork changes occur, the administrator may update the routerconfiguration to include the changes. Because such manual updating ofthe router configuration may be time consuming, static routing may beused in a small network environment.

Several different environments may be used to complete the stepsaccomplished by the disclosed invention. FIG. 2 demonstrates astreamlined example of such an environment. A First Hardware Resource200 and a Second Hardware Resource 270 may be, or may be used forapplications and/or processes related to a Server, and may be part of agroup of resources, possibly part of a server cluster serviced by acommon Router 240. A Hosted Account 220 may be hosted using Serverresources in addition to Central/Shared Storage 210. An IP Address 230may be associated with the Hosted Account 220. A Routing Table 250 onthe Router 240 may contain a route/path used to direct network trafficfor the IP Address 230 to the Hosted Account 220.

A Provisioning System 260 may be used to assign the Hosted Account 220to the IP Address 230. The Provisioning System 260 may also use staticrouting to migrate the Hosted Account 220 and its associated IP Address230 from the First Hardware Resource 200 to a Second Hardware Resource270. This environment and its components, as described in detailelsewhere in this disclosure, may provide the structure for variousmeans for executing the steps involved in accomplishing the invention asdisclosed.

This environment may also include an autonomous system. The autonomoussystem may be a collection of connected IP routing prefixes under thecontrol of one or more network operators that presents a common, clearlydefined routing policy.

The current system may also reside within a Virtual Local Area Network(VLAN) environment, which may be a group of hosts with a common set ofrequirements that communicate as if they were attached to the Broadcastdomain, regardless of their physical location.

As previously described, the First Hardware Resource 200 and a SecondHardware Resource 270 may be part of a group of resources, possibly partof a server cluster serviced by a common Router 240. However, in apossible VLAN environment, these resources, although having the sameattributes as a Local Area Network (LAN) may allow for resources to begrouped together, even if they are not located on the same router and/ornetwork switch. This would allow reconfiguration to be accomplishedthrough software or other means instead of physically relocatingdevices/resources.

The First Hardware Resource 200 and Second Hardware Resource 270 may beany device, process, application or piece of information such as aServer or any other network hardware resource which may facilitate theuse of a computer network and may be remotely accessed from anothercomputer or other network resource. FIG. 2 shows the First HardwareResource 200 and Second Hardware Resource 270 as servers fordemonstrative purposes only, possibly representing the Server containingand/or sharing resources for the Shared/Central Storage 210, and shouldin no way limit the scope of the current invention.

The First Hardware Resource 200 and/or Second Hardware Resource 270 maybe the Server or may be used for applications and/or processes relatedto server functionality and may include any combination of known orlater developed server technologies or formats capable of providingaccess to the Hosted Account 220 via static routing placed on theupstream Router 240 as disclosed elsewhere in this specification.

Such technologies or formats may include, but are not limited to sharedhosting, virtual dedicated hosting, dedicated hosting, or anycombination thereof. The type of Server should likewise not be limited,and may include a Web Hosting Server, a DNS Server, a Mail Server, otherServers now known or later developed in the art, or any combinationthereof.

The Central/Shared Storage 210 may be any computer components, devices,and/or recording media that may retain digital data used for computingfor some interval of time. The storage may be capable of hosting theHosted Account 220 on a single machine or in a cluster of computers overthe network.

As non-limiting examples, the Central/Shared Storage 210 may beNetwork-Attached Storage (“NAS”—self contained file level computer datastorage connected to and supplying a computer network file-based datastorage services), a Storage Area Network (“SAN”—an architecture toattach remote computer storage devices to servers in such a way that thedevices appear as locally attached), any combination thereof such as aNAS-SAN hybrid, or any other means of central/shared storage now knownor later developed. To include and simplify the depiction of suchenvironments in FIG. 2 and subsequent figures, the Central/SharedStorage 210 is labeled between the two networked hardware resources.This should in no way limit the scope of the current invention.

The Hosted Account 220 may be an account on a hosting service or virtualhosting service communicatively coupled to a network. Each account maysit on its own partition or section/place on a Server to keep itseparate from other accounts, or may be hosted on its own dedicatedServer. Just as the Server may be any Server known in the art, theHosted Account 220 may likewise be any account associated with such aServer. Thus, the Hosted Account 220 may be an account for a web hostingservice, an email account, a DNS administrator account, etc. As anon-limiting example, the Hosted Account 220 is shown in FIG. 2 andsubsequent figures as “exampleaccount.com.”

The IP Address 230 may be a numerical identification or logical addressthat is assigned to devices participating in a computer networkutilizing the Internet Protocol for communication between its nodes. TheIP Address 230 may serve multiple hostnames on a single machine with asingle IP address, may include a requested hostname as part of therequest to determine the Hosted Account 220 to display to a customerusing the Hosted Account 220, or may use IP-based virtual hosting, alsoknown as dedicated IP hosting, in which each virtual host has adifferent IP address.

In the Context of the IP Address 230, hostnames and IP addresses may notnecessarily match on a one-to-one basis. Many hostnames may correspondto a single IP address. Combined with shared and/or virtual hosting,this may allow a single machine to serve many accounts via HostedAccounts 220. Alternatively, a single hostname may correspond to many IPaddresses. This may be used to facilitate fault tolerance and loaddistribution, and may also allow a site to move physical locationseamlessly.

As a non-limiting example, the IP Address 230 is shown in FIG. 2 andsubsequent figures in the simplified form of 123.456.0, and is shown forexample purposes to be associated with and/or bound to Hosted Account220 “exampleaccount.com.”

The Router 240 may be any computer or network component whose softwareand hardware are tailored to the task of routing and forwardinginformation. The Routing Table 250 may be an electronic table, fileand/or database type object stored in the Router 240 or a networkedcomputer which stores the routes and/or metrics associated with thoseroutes to particular network destinations. The information on theRouting Table 250 may further include information about the utilizationof the network around it. The construction of the Routing Table 250 maybe the primary goal of routing protocols and static routes, discussed inmore detail elsewhere in this application.

As a non-limiting example, the simplified Routing Table 250 on Router240 shows 123.456.0 being routed to the First Hardware Resource 200 inFIG. 2 and subsequent figures and routed to the Second Hardware Resource270 in FIG. 6.

The Provisioning System 260 may be any system capable of a datamigration process, which may further include transferring data,applications and/or processes between storage types, formats and/orcomputer systems. The Provisioning System 260 may also assign the HostedAccount 220 to the IP Address 230. To include and simplify the depictionof environments such as that seen in FIG. 2 and subsequent figures, theProvisioning System 260 is labeled between the two networked hardwareresources used in the migration.

Many steps may be used to accomplish such a migration. These steps mayinclude, but are not limited to any combination of the following:selecting a resource from a pool of available resources; loading theappropriate software such as operating system, device drivers,middleware, applications and/or processes; appropriately customizing andconfiguring the system software to create or change a configuration forthe resource, and change its parameters; auditing the system, such asensuring compliance or install patches, starting the resource, making afile system ready for use by an operating system, reading certain indexdata structures from storage into memory prior to mounting, mapping anassociated drive, verifying data to determine whether the data wasaccurately translated, is complete and supports processes in the newsystem/resource and running both systems in parallel to identify areasof disparity and forestall erroneous data loss; mapping data from theold system/resource to the new system/resource; providing a design fordata extraction, where data is read from the old system/resource; dataloading, where data is written to the new system/resource and relatingold data formats to the new system/resource's formats and requirements,as well as any other known or later developed migration steps. Such datamigration phases including design, extraction, cleansing, load andverification for applications may be repeated several times before thenew system is deployed.

It should be noted that the migration accomplished by any combination ofthe steps listed above is not limited to migrating applications. Anyprocess, such as Server processes may likewise be migrated using anycombination of the previously listed steps. As a non-limiting example,in a shared hosting server environment, processes such as serverprocesses may be migrated rather than requiring a migration of an entireoperating system.

Furthermore, during the migration, if the resources/systems haveread/write capabilities (permissions or access rights which control theability of applications, processes and/or accounts on the resource to beviewed and/or changes made to the contents of the file system), a freezemay be placed on the First Hardware Resource 200 and/or affectedapplications, processes and/or accounts, while a combination of theabove listed steps is used to migrate the affected applications,processes and/or accounts, until they are successfully configured,migrated and verified on the Second Hardware Resource 270.

As a non-limiting example, the Provisioning System 260 in the currentinvention may accomplish migration by selecting a Second HardwareResource 270 from a pool of available hardware resources to migrate the“exampleaccount.com” account and IP 123.456.0 and any associatedapplications or processes. Appropriate software or processes may beloaded onto the Second Hardware Resource 270, and the software andsystem may be appropriately customized, configured and generally madeready for operation.

The Provisioning System 260 may then accept instructions for mapping thedata to be migrated and the route/path on the Routing Table 250 from aFirst Hardware Resource 200 to a Second Hardware Resource 270. Data,applications and/or processes may then be extracted from the FirstHardware Resource 200 and loaded onto the Second Hardware Resource 270with the route being updated appropriately through static routing. TheFirst Hardware Resource 200 may be frozen as described above during anyportion of this migration.

The Provisioning System 260 may likewise instantiate and configure theIP Address 230 for migration. The IP Address 230 may then facilitate andallow data such as the Hosted Account 220 to move physical locationseamlessly. The Routing Table 250 may then be updated to reflect thedestination resource as the Second Hardware Resource 270. It should benoted in this example environment that any Domain Name System (DNS)entries would not be affected since the IP address 230 associated withthe account has not changed.

An example embodiment shown in FIG. 3 shows that the step of managingthe IP Address 230 using an attached Loopback Interface (Step 300) maybe included.

The Loopback Interface 400, seen in FIG. 4 may be a virtual interfaceused for management purposes. The Loopback Interface 400 may be assignedan address, in this example 123.456.0. This IP Address 230 may beaccessed from management equipment, software or a control panel over anetwork, such as the example control panel interfaces seen in theexample embodiments below. The Loopback Interface 400 may not berequired to be assigned to any of the real interfaces on the device suchas the First Hardware Resource 200, the Second Hardware Resource 270 orany other network resources.

Network components which use the Loopback Interface 400 may send orreceive traffic using the address assigned to the virtual interface asopposed to the address on the physical interface through which thetraffic passes. Network hardware resources may be configured withmultiple physical network interfaces, or virtual network interfaces onthe same physical interface.

An example embodiment shown in FIGS. 5 and 6 shows that the step ofusing static routing to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 using static routing (Step110) may be accomplished without affecting a DNS entry of a customerusing the Hosted Account 220 (Step 500).

A customer using the Hosted Account 220 may be an individual or anentity including a person, a business, a governmental institution, aneducational institution, a non-profit organization, or a socialorganization or any other individual or organization that may access anduse the Hosted Account 220.

The DNS may distribute the responsibility for assigning domain names andmay map them to IP networks by allowing an authoritative name server foreach domain to keep track of its own changes. The DNS may be maintainedby a distributed database system, which may use a client-server model.Static addressing may be, but is not necessarily used in someinfrastructure situations, such as finding the DNS directory host thatmay translate domain names to IP addresses. Static addresses may also beused to locate servers inside the network environment.

The DNS may allow the assignment of domain names independent of aphysical routing hierarchy represented by the numerical IP address.Because of this, hyperlinks and Internet contact information can remainthe same, whatever the current IP routing arrangements may be. Thus themigration of the Hosted Account 220 and the IP Address 230 may beaccomplished without the customer's DNS entries being affected.

An example embodiment shown in FIG. 7 shows that the step of hosting aHosted Account 220 on a First Hardware Resource 200 (Step 100) may befollowed by a step of the Server providing access to the Hosted Account220 via a static route placed on the upstream Router 240 (Step 700).

FIG. 8 shows an example control panel interface that may be usedtogether with the structure disclosed in FIGS. 2, 4, 6, 22 and 36 fornetwork management of the current invention. This control panelinterface may be a computer user interface that utilizes a control panelmetaphor to allow the user control of software and hardware features,which may control network management, in this example.

The control panel may be accessible via any application or systemincluding, but not limited to a computer, laptop, telephone, handhelddevice, etc. that may access and display a possibly remote service on aserver or other computer system using a network, and may includeadditional stand-alone programs.

The user interface may be any graphical, textual and/or auditoryinformation a computer program presents to the user, and the controlsequences such as keystrokes, movements of the computer mouse,selections with a touch screen etc. used to control the program. Theinterface may further include viewing and editing capabilities.

Examples of such interfaces include any known or later developedcombination of Graphical User Interfaces (GUI) or Web-based userinterfaces, Touch interfaces, Conversational Interface Agents, Live UserInterfaces (LUI), Command line interfaces, Non-command user interfaces,Object-oriented User Interfaces (OOUI) or Voice user interfaces.

Likewise, information may be input and displayed using methods otherthan that seen in the following example interfaces. An example interfacemay show information being entered from a drop-down list, but this orany other information could be accepted using any field, widget and/orcontrol used in such interfaces, including but not limited to atext-box, text field, button, hyper-link, list, drop-down list,check-box, radio button, data grid, icon, graphical image, embeddedlink, etc. The example interface in FIG. 8 and similar examplesthroughout this disclosure are not intended to and should not limit thescope of the disclosed invention.

For example, FIG. 8 shows an example user interface that may bedisplayed as a network management control panel and used together withthe structure disclosed in FIGS. 2, 4, 6, 22 and 36. This interface,with the disclosed structure, may be used to enable the customer usingthe Hosted Account 220 to set the static route placed on the upstreamRouter 240 by identifying the First Hardware Resource 200 as thehardware resource and/or Server which provides access to the HostedAccount 220 and its associated IP Address 230 (Step 700).

An example embodiment shown in FIG. 9 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may be preceded by a stepof establishing a Server on the Second Hardware Resource 270 (Step 900).

FIG. 10 shows an example user interface using the disclosed structurethat may be used to establish a Server on the Second Hardware Resource270 (Step 900). For example, a customer using Hosted Account 220“exampleaccount.com” may use a series of drop-down lists to select asource First Hardware Resource 200 and destination Second HardwareResource 270 to establish a Server on the Second Hardware Resource 270.After selecting the source and destination hardware resources, thecustomer may then perform any of the previously disclosed migrationsteps and update the configuration of hardware resources, possibly byclicking a button on the interface.

An example embodiment shown in FIG. 11 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may be preceded by a stepof instantiating the IP Address 230 to be migrated to the SecondHardware Resource 270 (Step 1100).

FIG. 12 shows an example user interface using the disclosed structurewhich may be used to instantiate the IP Address 230 to be migrated tothe Second Hardware Resource 270 (Step 1100). For example, a customerusing “exampleaccount.com” may use the Provisioning System 260 toperform the creation of an instance of the IP 123.456.0 on the SecondHardware Resource 270.

In this example embodiment, the Provisioning System 260 may extrapolateinformation previously entered into the control panel interface by thecustomer to determine the IP Address 230 and the destination hardwareresource on which to instantiate the IP Address 230. The customer maythen perform any of the previously disclosed migration steps and confirmthe instantiation of the IP Address 230, possibly by clicking a buttonon the interface.

An example embodiment shown in FIG. 13 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may preceded by a step ofperforming mounting and access checks for a Central/Shared Storage 210associated with the IP Address 230 and the Hosted Account 220 (Step1300).

FIG. 14 shows an example user interface using the disclosed structurewhich may be used to perform mounting and access checks for aCentral/Shared Storage 210 associated with the IP Address 230 and theHosted Account 220 (Step 1300). For example, the progress of both checksmay be displayed as they are performed by the Provisioning System 260.At the completion, the customer using the Hosted Account 220 may thenperform any of the previously disclosed migration steps and confirmcompletion of the mounting and access checks, possibly by clicking abutton on the interface.

An example embodiment shown in FIG. 15 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may be preceded by a stepof configuring local processes on and verifying proper operation of theSecond Hardware Resource 270 (Step 1500).

FIG. 16 shows an example user interface using the disclosed structurewhich may be used to configure local processes on and verify properoperation of the Second Hardware Resource 270 (Step 1500). For example,the progress of both the configuration and verification may be displayedas it is performed by the Provisioning System 260. At the completion,the customer using the Hosted Account 220 may then perform any of thepreviously disclosed migration steps and confirm completion of theconfiguration and verification, possibly by clicking a button on theinterface.

An example embodiment shown in FIG. 17 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may be followed by a stepof updating a Routing Table 250 on a Router 240 upstream so that the IPAddress 230 migrated is serviced by the Second Hardware Resource 270,thereby accomplishing a route swing (Step 1700).

FIG. 18 shows an example user interface using the disclosed structurewhich may be used to update a Routing Table 250 on a Router 240 upstreamusing static routing so that the IP Address 230 migrated is serviced bythe Second Hardware Resource 270, thereby accomplishing a route swing(Step 1700). For example, a customer using the Hosted Account 220 mayselect from drop-down menus a source First Hardware Resource 200 and adestination Second Hardware Resource 270. The static route may then beupdated on the Routing Table 250 to accomplish the route swing (Step1700). The customer may then perform any of the previously disclosedmigration steps and confirm completion of the configuration and updatethe static route possibly by clicking a button on the interface.

An example embodiment shown in FIG. 19 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 (Step 110) may be followed by a stepof removing configuration data, removing processes and removing unneededdata mounts on the First Hardware Resource 200 (Step 1900).

FIG. 20 shows an example user interface using the disclosed structurewhich may be used to remove configuration data, processes and unneededdata mounts on the First Hardware Resource 200 (Step 1900). For example,the progress of the removal of configuration data, processes andunneeded data mounts on the First Hardware Resource 200 (Step 1900) maybe displayed as it is performed by the Provisioning System 260. At thecompletion, the customer using the Hosted Account 220 may then performany of the previously disclosed migration steps and confirm completionof the removal of configuration data, processes and unneeded datamounts, possibly by clicking a button on the interface.

A Method of Using Routing Protocols to Migrate a Shared Hosting Account

Several different methods may be used to provide and manage thedisclosed invention. In an example embodiment illustrated in FIG. 21, aHosted Account 220 on a First Hardware Resource 200 may be associatedwith an IP Address 230 (Step 100). Routing Protocols may then be used tomigrate the Hosted Account 220 and the associated IP Address 230 to aSecond Hardware Resource (Step 2100).

A Routing Protocol may gather and share the routing information used tomaintain and update routing tables. That routing information may in turnbe used to route a routed protocol to its final destination. A RoutingProtocol may also be a formula used by routers to determine theappropriate path onto which data should be forwarded and may specify howrouters report changes and share information with other routers in anetwork that they can reach.

Unlike static routing where all routing decisions may be required to bepredetermined and remain static, a routing protocol may allow thenetwork to dynamically adjust to changing conditions. This may beaccomplished via an announcement by the routing protocol to an upstreamrouter that may be updated appropriately. A Routing Protocol may be usedin a large network environment, since manual updating of the Router maynot be required.

Routing Protocols may be divided into link-state Routing Protocols anddistance vector Routing Protocols. A link-state protocol may uselink-state routing so that every node constructs a map of theconnectivity of the network, in the form of a graph showing which nodesare connected to which other nodes. Switching nodes, such as a router inthe network, may perform the link-state protocol. Link-state routing mayrequire each switching node in the network to send its information aboutits neighbors to the entire network.

Each node may then independently calculate the best next hop from it forevery possible destination in the network, using only its local copy ofthe map, and without communicating with any other node. The collectionof best next hops may form the routing table for the node. Examples oflink-state protocols may include, but are not limited to Open ShortestPath First (OSPF) and Intermediate System to Intermediate System(IS-IS).

This may be contrasted with distance-vector Routing Protocols, which maywork by having each node share its routing table with its neighbors tocalculate paths using less computational complexity and messageoverhead. In a link-state protocol, the only information passed betweenthe nodes may be information used to construct the connectivity maps.Examples of distance-vector Routing Protocols may include, but are notlimited to Routing Information Protocol (RIP), Interior Gateway RoutingProtocol (IGRP), Exterior Gateway Protocol (EGP) and Border GatewayProtocol (BGP).

Several different environments may be used to complete the stepsaccomplished by the disclosed invention. FIG. 22 demonstrates astreamlined example of such an environment. A First Hardware Resource200 and a Second Hardware Resource 270 may be, or may be used forapplications and/or processes related to a Server, and may be part of agroup of resources, possibly part of a server cluster serviced by acommon Router 240. A Hosted Account 220 may be hosted using Serverresources in addition to Central/Shared Storage 210. An IP Address 230may be associated with the Hosted Account 220. A Routing Table 250 on aRouter 240 may contain a route/path used to direct network traffic forthe IP Address 230 to the Hosted Account 220. This Routing Table 250 maybe sent dynamic announcements about the network using the RoutingProtocol 2200.

A Provisioning System 260 may be used to assign the Hosted Account 220to the IP Address 230. The Provisioning System may also migrate theHosted Account 220 and its associated IP Address 230 from the FirstHardware Resource 200 to a Second Hardware Resource 270 using a dynamicannouncement of a Routing Protocol 2200 substantially as describedabove. This environment and its components, as described in more detailelsewhere in this disclosure, may provide the structure for variousmeans for executing the steps involved in accomplishing the invention asdisclosed.

This environment works on substantially the same principles as thosedisclosed regarding FIGS. 2, 4 and 6. However, the use of the RoutingProtocol 2200 to send dynamic announcements to the upstream Router 240introduces notable differences in the environment shown in FIG. 22.

Specifically, rather than using a static route, data may be extractedfrom the First Hardware Resource 200 and loaded onto the Second HardwareResource 270 with the route being determined via an announcement by theRouting Protocol 2200 to an upstream Router 240 and updating the RoutingTable 250 on the upstream Router 240 appropriately. Similarly, ratherthan using a static route, access to the Hosted Account 220 may beaccomplished via an announcement by the routing protocol to an upstreamRouter 240 and the Routing Table 250 on the upstream Router 240 may beupdated appropriately using the Routing Protocol 2200. This environmentmay also include an autonomous system and reside within a VLANenvironment as previously described.

An example embodiment shown in FIG. 23 shows that the step of managingthe associated IP Address 230 using an attached Loopback Interface 400(Step 2300) as previously disclosed may be included in an environment inwhich Routing Protocols 2200 are used to migrate the Hosted Account 220to the Second Hardware Resource 270 (Step 2100).

An example embodiment shown in FIG. 24 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 (Step 2100) may beaccomplished without affecting a DNS entry of a customer using theHosted Account 220 (Step 2400) substantially similar to that previouslydisclosed regarding FIG. 6.

An example embodiment shown in FIG. 25 shows that the step of hosting aHosted Account 220 on a First Hardware Resource 200 (Step 100) may befollowed by a step of the Server providing access to the Hosted Account220 via a dynamic announcement to a Router 240 upstream from the Server(Step 2500).

FIG. 26 shows an example user interface using the disclosed structurewhich may be used to enable the customer using the Hosted Account 220 tosend a dynamic announcement to the upstream Router 240 by identifyingthe First Hardware Resource 200 as the hardware resource and/or Serverwhich provides access to the Hosted Account 220 and its associated IPAddress 230 (Step 2500).

An example embodiment shown in FIG. 27 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 (Step 2100) may bepreceded by a step of establishing a Server on the Second HardwareResource 270 (Step 2700). An interface substantially similar to thatshown in FIG. 10 and described in detail elsewhere in this applicationmay be used to accomplish this step.

An example embodiment shown in FIG. 28 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 (Step 2100) may precededby a step of instantiating the IP Address 230 to be migrated to theSecond Hardware Resource 270 (Step 2800). An interface substantiallysimilar to that shown in FIG. 12 and described in detail elsewhere inthis application may be used to accomplish this step.

An example embodiment shown in FIG. 29 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 (Step 2100) may bepreceded by a step of performing mounting and access checks for a SharedStorage 210 associated with the IP Address 230 and the Hosted Account220 (Step 2900). An interface substantially similar to that shown inFIG. 14 and described in detail elsewhere in this application may beused to accomplish this step.

An example embodiment shown in FIG. 30 shows that the step of migratingthe Hosted Account 220 and the IP Address 230 to a Second HardwareResource 270 using a Routing Protocol 2200 (Step 2100) may be precededby a steps of configuring local processes on and verifying properoperation of the New Hardware Resource 270 (Step 3000). An interfacesubstantially similar to that shown in FIG. 16 and described in detailelsewhere in this application may be used to accomplish this step.

An example embodiment shown in FIG. 31 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 (Step 2100) may befollowed by a step of updating a Routing Table 250 on the upstreamRouter 240 using the Routing Protocol 2200 so that the IP Address 230migrated is serviced by the Second Hardware Resource 270, therebyaccomplishing a route swing (Step 3100).

FIG. 32 shows an example user interface using the disclosed structurethat may be used to update a Routing Table 250 on a Router 240 upstreamusing the Routing Protocol 2200 so that the IP Address 230 migrated isserviced by the Second Hardware Resource 270, thereby accomplishing aroute swing (Step 3100). For example, a customer using the HostedAccount 220 may select from drop-down menus a source First HardwareResource 200 and a destination Second Hardware Resource 270. The dynamicannouncement may then be sent to update the Routing Table 250 on theRouter 240 to accomplish the route swing (Step 3100). The customer maythen perform any of the previously disclosed migration steps and confirmcompletion of the configuration and updated dynamic announcement to theRouter 240 possibly by clicking a button on the interface.

An example embodiment shown in FIG. 33 shows that the step of using aRouting Protocol to migrate the Hosted Account 220 and the IP Address230 to a Second Hardware Resource 270 (Step 2100) may be followed by thesteps of removing configuration data, removing processes, removingunneeded data mounts and removing a dynamic announcement to the Router240 upstream from the First Hardware Resource 200 (Step 3300).

FIG. 34 shows an example user interface using the disclosed structurethat may be used to remove configuration data, processes and unneededdata mounts on the First Hardware Resource 200 (Step 3300). For example,the progress of the removal of configuration data, processes, unneededdata mounts and dynamic announcement on the First Hardware Resource 200(Step 3300) may be displayed as the Provisioning System 260 performs it.At the completion, the customer using the Hosted Account 220 may thenperform any of the previously disclosed migration steps and confirmcompletion of the removal of configuration data, processes, unneededdata mounts and dynamic announcement, possibly by clicking a button onthe interface.

A Method of Using Static Routing to Optimize Resource Utilization

Several different methods may be used to provide and manage thedisclosed invention. In an example embodiment illustrated in FIG. 35, aHosted Account 220 may be hosted on a First Hardware Resource 200 withina group of resources. The Hosted Account 220 may be associated with anIP Address 230 (Step 100). An alert of a network resource utilizationchange affecting the group of resources may be received (Step 3500).Static routing may then be used to migrate the Hosted Account 220 andthe IP Address 230 to a Second Hardware Resource 270 in response to thenetwork resource utilization change (Step 3510).

Several different environments may be used to complete the stepsaccomplished by the disclosed invention. FIG. 36 demonstrates astreamlined example of such an environment. A First Hardware Resource200 and a Second Hardware Resource 270 may be, or may be used forapplications and/or processes related to a Server, and may be part of agroup of resources, possibly part of a server cluster serviced by acommon Router 240. A group of Hosted Accounts 220 may be hosted usingthe Server resources.

In the interest of simplifying the current environment for examplepurposes, additional components of the environment shown and describedin relation to FIGS. 2, 4, 6 and 22 are not shown in FIG. 36, but may beincluded. For example, an IP Address 230 may be associated with each ofthe Hosted Accounts 220. A Routing Table 250 on the Router 240 maycontain a route/path used to direct network traffic for the IP Address230 to the Hosted Account 220.

A Provisioning System 260 may be used to assign the Hosted Account 220to the IP Address 230. The Provisioning System 260 may also migrate theHosted Account 220 and its associated IP Address 230 from the FirstHardware Resource 200 to a Second Hardware Resource 270 and back usingstatic routing. This environment and its components, as described indetail elsewhere in this disclosure, may provide the structure forvarious means for executing the steps involved in accomplishing theinvention as disclosed.

As in previously disclosed environments, this environment may alsoinclude an autonomous system and/or may reside within a Virtual LocalArea Network (VLAN) environment as previously disclosed.

The Loopback Interface 400 previously disclosed may also be used formanagement datagrams, such as alarms, originating from the networkresources, which may be used to facilitate the alert of network resourceutilization changes affecting the group of resources. The IP Address 230may likewise be used to facilitate alerts of network resourceutilization changes such as fault tolerance and load distribution.

A metric may be used to determine a threshold at which an alert is usedto show a network resource utilization change. In the steady state, theServer may provide access to the Hosted Account 220 that may be bound tothe IP Address 230. The alert may be triggered when the state is nolonger a steady state, possibly an overload state.

A metric may be any variable assigned to network resources as a means ofranking them from best to worst or from most preferred to leastpreferred. The Router 240 may have and/or be used as part of themechanism for calculating a best resource to be used when there aremultiple available resources. Such metrics may also be used to determinewhen a migration to another hardware resource is recommended, and whichhardware resource is preferred.

For example, any combination of disclosed software and hardwareresources such as, but not limited to the Loopback Interface 400, IPAddress 230 and Router 240 may determine a steady state thresholdthrough monitored metrics which trigger an alert of a network resourceutilization change related to Account C, hosted on First HardwareResource 200 as shown in FIG. 36, and its associated IP Address 230. Thenetwork resource utilization change alert may be displayed to a customerwho may automatically or manually migrate Account C and its associatedIP Address 230 to the Second Hardware Resource 270 using static routingto update the route in the Routing Table 250 (Step 3510).

An example embodiment shown in FIG. 37 shows that the step of usingstatic routing to migrate the Hosted Account 220 and the IP Address 230to a Second Hardware Resource 270 in response to the network resourceutilization change (Step 3510) may be preceded by a step providing acontrol panel for a manual migration of the Hosted Account 220 andmanually updating a static route on a Router 240 upstream from the groupof resources (Step 3700).

FIG. 38 shows an example user interface using the disclosed structurewhich may be used to receive an alert of a network resource utilizationchange affecting the group of resources (Step 3500) and use staticrouting to migrate the Hosted Account 220 and the IP Address 230 to aSecond Hardware Resource 270 in response to the network resourceutilization change (Step 3510).

The example interface shown in FIG. 38 shows that many combinations ofsteps may be used to automatically or manually migrate the HostedAccount 220 and the IP Address 230 to a Second Hardware Resource 270 inresponse to the network resource utilization change (Step 3510). Thesystem may automatically calculate the best distribution of resourcesand the best migration strategy for such a distribution. Likewise, thesystem may automatically migrate the Hosted Account 220 and IP Address230 (Step 3510) according to the best-calculated migration anddistribution strategy.

To accomplish such a strategy, a customer using the example interfaceshown in FIG. 38 may only need to push the button to calculate the bestmigration and distribution strategy and confirm automatic migration ofthe Hosted Account 220 and the IP Address 230 to a Second HardwareResource 270 in response to the network resource utilization change(Step 3510). Similarly, the system may detect, calculate and apply sucha migration and distribution strategy without user input.

Another use of the interface in FIG. 38 may include selecting thehardware resources to be used in such a migration, possibly usingprovided drop-down menus, and confirming whether this is the bestmigration and distribution strategy by clicking a provided button.

A button may also be provided which allows the customer using the HostedAccount 220 to open a control panel to migrate the Hosted Account 220and Shared Hosting IP Account 230 manually in combination with updatingthe static route on a Routing Table 250.

The control panel may be any control panel disclosed in the currentspecification which allows the migration of the Hosted Account 220 andthe IP Address 230 to be migrated between hardware resources usingRouting Protocols 2200, or in combination with any migration controlpanel disclosed, known or later developed in the art. Likewise, themigration itself in step 3510 may be accomplished using any method formigration using static routing disclosed in the current specification.

An embodiment shown in FIG. 39 shows that the step of receiving an alertof a network resource utilization change affecting the group ofresources (Step 3500) may be modified to include the step of showing ahigh load and a lower load configuration available (Step 3900), and thatthe step of using static routing to migrate the Hosted Account 220 andthe IP Address 230 to a Second Hardware Resource 270 in response to thenetwork resource utilization change (Step 3510) may be followed by thestep of performing load balancing in response to the network resourceutilization change (Step 3910).

Load balancing may include the practice of distributing traffic amongmultiple resources in order to use bandwidth efficiently. Load balancingmay be implemented to alternate or distribute traffic between themultiple resources. The high load alert may be a metric that reflects ahigh amount of traffic utilizing a resource in a group of resources. Thebest configuration may then be reflected in the one with the lowest loador load distribution.

As a non-limiting example, FIG. 36 shows a streamlined configurationwith a group of hardware resources including a First Hardware Resource200 and a Second Hardware Resource 270 communicatively coupled to aRouter 240. The First Hardware Resource 200 may host 2 Hosted Accounts220, Account A and Account C, and the Second Hardware Resource 270 mayhost 2 accounts Account B and Account D.

The system may determine a high load on the First Hardware Resource 200and determine that the load may be balanced by automatically or manuallymigrating Account C to the Second Hardware Resource 220 using disclosedmethods for such migration using static routing.

FIG. 40 shows an example user interface using the disclosed structurewhich may be used to perform load balancing in response to the networkresource utilization change (Step 3910) including an alert of a highload and a lower load configuration available (Step 3900), which may bedisplayed to a customer, who may migrate the Hosted Account 220 and IPAddress 230 and update the route in the Routing Table 250. This may beaccomplished using drop-down menus to select the First Hardware Resource200 as the source and the Second Hardware Resource 270 as thedestination for the migration. The customer may then migrate the HostedAccount 220 and IP Address 230 to optimize and balance the load,possibly by clicking a button on the interface.

As shown in FIG. 40, the Provisioning System 260 may use metrics fromany combination of disclosed network software and hardware resourcessuch as, but not limited to the Loopback Interface 400, IP Address 230and Router 240 to determine the optimal parameters for load balancing,or any other available remedies for the detected network resourceutilization change. A button may be available on the user interface todetermine and apply such parameters automatically or manually. This maylikewise be applied to any other network resource utilization change oravailable remedies for metrics showing variance from steady state.

Several different approaches may be used to balance the availableresources. One such approach may allow the Hosted Account 220 to bemigrated to accomplish equalization of the load on the group ofresources. As a non-limiting example seen in FIG. 40, Account C may beautomatically or manually migrated to the Second Hardware Resource 270where the First Hardware Resource 200 may be using 90% of its resourcesaffecting load and the Second Hardware Resource may using 30% of itsresources affecting load.

In this example, the migration may accomplish use of 60% of theresources affecting load for the First Hardware Resource 200 and 60% ofresources affecting load for the Second Hardware Resource 270. If thesystem determines such a scenario, manual or automatic migration usingstatic routing may accomplish equalization of the load on the group ofresources.

In another example approach, the First Hardware Resource 200 may havethe highest load among the group of resources, the Second HardwareResource 270 may have the lowest load among the group of resources andthe Hosted Account 220 may be migrated using static routing from theFirst Hardware Resource 200 to the Second Hardware Resource 270 tobalance the load.

For example, Account C may be migrated to the Second Hardware Resource270 when it is detected that the highest use of resources affecting loadis on the First Hardware Resource, and the migration of Account C may beused to balance the load. Such an approach may be used to temporarilybalance the load. If the use of load-related resources on the FirstHardware Resource 200 is reduced at some point after the migration, theHosted Account 220 may be migrated back to the First Hardware Resource200 when the high load on the First Hardware Resource 200 has beenreduced to better accommodate the Hosted Account 220.

A Method Using Routing Protocols to Optimize Resource Utilization

Several different methods may be used to provide and manage thedisclosed invention. In an example embodiment illustrated in FIG. 41, aHosted Account 220 may be hosted on a First Hardware Resource 200 withina group of resources. The Hosted Account 220 may be associated with anIP Address 230 (Step 100). An alert of a network resource utilizationchange affecting the group of resources may be received (Step 3500). ARouting Protocol 2200 may then be used to migrate the Hosted Account 220and the IP Address 230 to a Second Hardware Resource 270 in response tothe network resource utilization change (Step 4100).

Several different environments may be used to complete the stepsaccomplished by the disclosed invention. The environment shown in FIG.36 and described elsewhere in this disclosure demonstrates a streamlinedexample of such an environment.

This environment works on substantially the same principles as thosedisclosed regarding FIG. 2 and subsequent like environments. However,the use of a Routing Protocol 2200 (not shown in FIG. 36) to senddynamic announcements to the upstream Router 240 introduces notabledifferences in the environment described in FIG. 36.

Specifically, rather than using a static route, data may be extractedfrom the First Hardware Resource 200 and loaded onto the Second HardwareResource 270 with the route being determined via an announcement by theRouting Protocol 2200 to a Router 240 upstream from the group ofresources and updating the Routing Table 250 on the upstream Router 240appropriately. Similarly, rather than using a static route, access tothe Hosted Account 220 may be accomplished via an announcement by therouting protocol to an upstream Router 240 and the Routing Table 250 onthe upstream Router 240 may be updated appropriately using the RoutingProtocol 2200. This environment may also include an autonomous systemand reside within a VLAN environment as previously described.

As in the example environment shown in FIG. 36, the Loopback Interface400 may be used in conjunction with other network resources andmonitored metrics to facilitate the alert of network resourceutilization changes affecting the group of resources.

For example, any combination of disclosed software and hardwareresources such as, but not limited to the Loopback Interface 400, IPAddress 230 and Router 240 may determine a steady state thresholdthrough monitored metrics which trigger an alert of a network resourceutilization change related to Account C, hosted on First HardwareResource 200 as shown in FIG. 36, and its associated IP Address 230. Thenetwork resource utilization change alert may be displayed to a customerwho may automatically or manually migrate Account C and its associatedIP Address 230 to the Second Hardware Resource 270 using a RoutingProtocol 2200 to update the route in the Routing Table 250 (Step 4100).

An example embodiment shown in FIG. 42 shows that the step of using aRouting Protocol 2200 to migrate the Hosted Account 220 and the IPAddress 230 to a Second Hardware Resource 270 in response to the networkresource utilization change (Step 4100) may be preceded by a stepproviding a control panel for a manual migration of the Hosted Account220 and manually updating a dynamic announcement sent to a Routerupstream from a Server on a Router 240 upstream from the group ofresources. (Step 4200). An interface substantially similar to that shownin FIG. 38 and described in detail elsewhere in this application may beused to accomplish this step.

An embodiment shown in FIG. 43 shows that the step of receiving an alertof a network resource utilization change affecting the group ofresources (Step 3500) may be modified to include the step of showing ahigh load and a lower load configuration available (Step 4300), and thatthe step of using a Routing Protocol 2200 to migrate the Hosted Account220 and the IP Address 230 to a Second Hardware Resource 270 in responseto the network resource utilization change (Step 4100) may be followedby the step of performing load balancing in response to the networkresource utilization change (Step 4310). An interface substantiallysimilar to that shown in FIG. 40 and described in detail elsewhere inthis application may be used to accomplish these steps.

As a non-limiting example, FIG. 36 shows a streamlined configurationwith a group of hardware resources including a First Hardware Resource200 and a Second Hardware Resource 270 communicatively coupled to aRouter 240. The First Hardware Resource 200 may host 2 Hosted Accounts220, Account A and Account C, and the Second Hardware Resource 270 mayhost 2 accounts Account B and Account D.

The system may determine a high load on the First Hardware Resource 200and determine that the load may be balanced by automatically or manuallymigrating Account C to the Second Hardware Resource 220 using disclosedmethods for such migration using a Routing Protocol 2200.

Several different approaches may be used to balance the availableresources. One such approach may allow the Hosted Account 220 to bemigrated to accomplish equalization of the load on the group ofresources. As a non-limiting example, Account C may be automatically ormanually migrated to the Second Hardware Resource 270 as seen in FIG. 40where the First Hardware Resource 200 may be using 90% of its resourcesaffecting load and the Second Hardware Resource may using 30% of itsresources affecting load.

In this example, the migration may accomplish use of 60% of theresources affecting load for the First Hardware Resource 200 and 60% ofresources affecting load for the Second Hardware Resource 270. If thesystem determines such a scenario, manual or automatic migration usingRouting Protocols 2200 may accomplish equalization of the load on thegroup of resources.

In another example approach, the First Hardware Resource 200 may havethe highest load among the group of resources, the Second HardwareResource 270 may have the lowest load among the group of resources andthe Hosted Account 220 may be migrated using Routing Protocols 2200 fromthe First Hardware Resource 200 to the Second Hardware Resource 270 tobalance the load.

For example, Account C may be migrated to the Second Hardware Resource270 when it is detected that the highest use of resources affecting loadis on the First Hardware Resource, and the migration of Account C may beused to balance the load. Such an approach may be used to temporarilybalance the load. If the use of load-related resources on the FirstHardware Resource 200 is reduced at some point after the migration, theHosted Account 220 may be migrated back to the First Hardware Resource200 when the high load on the First Hardware Resource 200 has beenreduced to better accommodate the Hosted Account 220.Other embodimentsand uses of the above inventions will be apparent to those havingordinary skill in the art upon consideration of the specification andpractice of the invention disclosed herein.
